To all whom t't may concern.'

Be it known that I, JOHN N. HAHN, a citizen of the United States, residing. at Cleveland, in the county of Cuyahoga-and State of Ohio,vhave invented certain new and useful Improvements in Machines for Making` Bottle-Wrappers, and do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same. l

My invention relates to a machine for making bottle wrappers, 'and the invention 'consists in a machine adapted to make and complete the Wrappers in a continuous operation, substantially as described and particularly as pointed out in the claims.

In the accompanying drawings Figure 1 is a plan of my machine more or less diagrammatic in its outlines, and Fig. 2 is a longitudinal sectional elevation of the machine. Fig. 3 is a plan view ofthe paster or pasting device. Fig. 4 is a plan view of a finished wrapper and as made by the machine. Fig. 5 shows the outer paper covering or envelop without the corrugated board or body and pasted as it comes through the machine. Fig. 6 shows the wrapper as partially closed for use, the same being folded and pasted along its side edges but with the ends open, and Fig. 7 shows the sides and ends closed as when it contains a bottle or' other article. Fig. 8 is a cross section of the hopper.

The commercial article is shown in Fig. 4, in which l'orm it is adapted to be folded into a rectangular box like wrapper or parcel of tubular shape, by moistening the free pasted edge thereof like an envelop, and pasts ing it upon the back of the opposite edge of the wrapper. Then il desired the tube may be flattened down on the line of its transverse corner creases and in this t'orm it would be in very excellent shape for shipping il it were preferred in this way. However, the flat open form in Fig. 4 is the most convenient for packing, und less room is occupied than with a flattened folded tube. Now,.referring to the drawings, it will be seen that it contains, first, an endless carrier C adapted to travel over a roller 2 at its initial end and roller 3 at its delivery end from this point on the stock passes between the upper series of rolls 4 and lower series 5, and plates G and 7 are provided in the spaces'betwcen said rollers which bridge said space and form a close passage way in which the pasted cover is adhered to the corrugated board. Between therollers 2 and 3 there is a long table or equivalent support 8 over which the carricr moves, and D is a hopper or receptacle adapted to deliver the corrugated blanks 9, which constitute the body of the wrapper to the carrier. Howeven'any suitable means may be employed for automatically delivering the said corrugated board or pieces from said 4hopper or other device upon the carrier, but in this instance I employ a simple construction which is always 'sure to operate and which takes only the lower of the l series of said boards in the hopper and carriers and l repeats this action at intervals while the carrier isinv operation. To this end I provide the carrier withtransverse engaging strips or pieces 10, .which has less I thickness than the boards so that they will pass under i the superposed boards while'the lower one is being i reached thereby. A few lugs across the face of the carrier instead of the plates or strips 10 might suffice, and any suitable means other than what is shown may be employed for this purpose, as, for example, a mechan- .ism which will automatically place the boards in proper position upon the carrier at suitable intervals.

The boards or body parts 9 'of thewrapper are madeof suitable corrugated paper, pasteboard, carboard or the like, and are preferably of a single thickness of paper borne along by the carrier to the double set of rollers above described. i I

As already set forth, the invention is designed to produce a Wrapper for bottles and other articles made up as corrugated body or boards 9, an outerA sheet or envelop 12, and4 preferably corrugated end fiaps 14. These cut to sine and adapted to run with the corrugations in I `the direction of travel, and in this manner they are l shown in Figs. 4 to 7 inclusive, and comprising the said u several parts are united as seen in Fig. 4 preparatory to folding as in Figs. 6 and 7, and as an initial requirement to getting these parts together as in Fig. 4, it is necessary to produce or provide the envelop blank 12. Said blank is cut by a roller 15, or its equivalent from the continuous sheet of paper proceeding from the roll of paper lalso marked 16 for identification. Any suitable kind of paper may be used to form the envelop or covering l2, and in its transit to the pasting and rollingmechanism it is shown in this instance as passing between two sets of printing rollers E and E and G and Gf, and, ink

distributors 17 and 18, respectively. In this manner I .Y am enabled to print the cover in at least two differentV colors", and I might by continuing ythe rolls print in several colors as well. From the said printing rolls the paper passes over a rotating pastor H, which has a suitable paste receptacle h and is adapted to turn continually and constructed to paste upon lines indicated particularly in Fig. 5. In said figure there are shown two parallel pasting lines 18 adapted to adhere the cover or envelop to the board 9, two outer patches of-paste 19 to attach the end flaps 14, a cross strip 20 to paste or secure the edge of the paper on board 9 between said flaps, and the envelop paste line 21, which is not designed to be used until the box is made for use, as shown in Fig. 6, and in which case tliis edge of the paper is lapped over upon the edge 21 thereof so as to make a y single tube, Fig. 6. This leaves the end flaps 14 and certain portions m of unpasted paper at the said ends in position to fold over said flaps when they are turned down to closing position. The roller paster H is therefore provided with a longitudinal strip or portion 22 to e tinuous paste lines 18, and segments 24 adapted to paste the corner 19, Fig. 5. The strip 22 is supposed to be -wide enough to apply paste upon both strips and 21, the plan being to sever the paper transversely on this pasting line, thus leaving a portion of pasted surface with ea'ch cover or envelop. v

Now, having pasted the continuous sheet of paper 16, said paper is passed between rollers 3 and 4 and 4 and 5 successively, and plates 6 and 7 are placed between these' rollers to bring the said sheet flat down upon the corresponding corrugated board 9 practically from end to end thereof,A and as the said parts pass through and between the said rollers and plates the pasted sheet becomes adhered to the said board. Among the lower rollers I.locate a creasing roller N, which has creasing blades n spaced apart equal to the width of the sides of the wrapper or package. TheseA creases become the breaking lines for the corrugatons of the board, and are directly in the corners thereof when the board is bent to form the box. This also makes all the sides uniform and a perfectly square box in cross section. Of course boxes of any size large or small may be made by this operation, and the crea-ser may be exchanged for another wherein the blades are nearer together or farther apart than in this case.

Now, having creased the board and the pasting of the. paper upon the back of the board being completed thev product, which' is the continuous sheet and the boards adhered thereto, is passed through beneath the severingl roll 15 and the paper is cut into lengths as mu'ch longer than'tne board as pasted by the blade 26 thereon. Otherwise the sheet of paper is supposed to have the requisite width to provide folding ends m as 'shown when the paper has been severed and cut into suitable lengths for the covering. This being done the wrapper is commercially, finished and is delivered over the inclined board 27 at the tail of the machine to be lcarried away as may be 'found most convenient. The real feed of endless sheet 16 from the roll is by the pull of the several rolls 3, 4,and 5 and so on, and power may be applied through roll 2 or 4 as may be found convenient.

The end flaps 14 are contained in suitable hoppers d at the sides of hopper D for the body boards, and separate endless carriersl 30 are provided therefor at the sides of the main carrier C. These several carriers or con veyers may be oi any suitable construction and in this i instance employ sprocket chains and wheels to drive the same, separate cross strips 31 on the carriers 30 reach the lower pieces 14 and convey them along in the right relation to the board 9 on carrier C to be pasted upon cover m without changing position. In the feed of cover and these parts itis necessary to sec that the right relations are maintained so as to always bring pieces 14 to the places pasted therefor on the cover.

The paste used may be of any suitable kind, and the several rollers for pressing the parts together are at least as long as the full width of the wrapper, including the end flaps.
